FSA Gravity SX Tapered Headset
Basically, the FSA Gravity SX is the mullet of headsets. It's business up top and one big party in the bottom.
The lower cup is 1.5" and is a traditional external press-in style. It rolls on heavy duty oversized ball bearings.
The upper cup is 1 1/8" and is an internal style. This tapered headset will only work with a fork that has a tapered steer tube. Depending on your local vernacular, internal in this case translates to mean Zero Stack. The top bearing is fully sealed and ultra smooth.
Total in-house measured weight including star fangled nut is 230g.
